①歪み対策として、画像の様に裏面に鉄板を2本入れてください。
鉄板は長さ110ｃｍ・幅2.5ｃｍ以上・厚み6ｍｍ以上。
ビスは長さ2ｃｍの物を使用し、5ｃｍ間隔に打ち、1本につき23本取り付けてください。
(テーブル1台につき合計46本)
②また、今回納品されたもので裏面に背割れがあるもの、ないものがありましたが、
次回生産分はより歪みづらい方で全て統一して生産願います。
1. As a measure of preventing distortion, please put 2 iron boards at back similar to the one in the picture.
The iron board is 110 centimeters in length, 2.3 centimeters in width and more than 6 millimeters in thickness.
Use screw that is as long as 2 meters. Hit it by 5 centimeter interval and set 23 pieces per each.
(46 pieces in total per table)
2. For the ones that were delivered this time, some had a crack at the back and others did not have it.
Would you produce all by the one where it is difficult to be distorted from next time?
